This painting by John Knox (1778-1845) shows the sons of Colin Campbell of Colgrain standing around the ice house above Camis Eskan. He bought the estate in 1836 from James Dennistoun, the last of the Dennistouns of Colgrain, whose family had owned the land for over 500 years. The Dennistouns were granted the lands by the first Stuart king Robert II, who had married into the family, and whose son Robert III and all future Kings would have Dennistoun blood in their veins.
